Mounting device for hard disk drive

ABSTRACT

A mounting device comprises two sidewalls, a connecting portion defining a receiving slot, a fixing member, and a latching member slidably received in the receiving slot. A blocking piece and a connecting wall are connected between a top wall and a bottom wall of the receiving slot. A first end of the fixing member forming two projections is pivotably connected to the first end of the connecting portion. The projections are received in the receiving slot. A tab extends from a second end of the fixing member. The latching member comprises a plate blocked by the blocking piece, and an extension piece blocked by the connecting wall. The fixing member is pivoted toward the latching member to allow the projections to extend out of the receiving slot. The latching member is slid toward the fixing member to block the tab.

BACKGROUND

1. Technical Field

DETAILED DESCRIPTION

The disclosure, comprising the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”

FIGS. 1 and 2 show an embodiment of a mounting device 10 for mounting a hard disk drive (HDD) 20 and a conversion card 30.

The mounting device 10 comprises two sidewalls 12, a connecting portion 14 connected between first end portions of the sidewalls 12, a fixing member 16 pivotably mounted to a first end portion of the connecting portion 14, and a latching member 18 slidably mounted to a second end portion of the connecting portion 14.

A second end portion of each sidewall 12 defines a through hole 120.

The connecting portion 14 comprises a top wall 142, a bottom wall 144, and a connecting wall 152 between second end portions of the top wall 142 and the bottom wall 144. The connecting portion 14 defines a receiving slot 140 extending through the first end portion of the connecting portion 14. A blocking piece 150 is connected between the top wall 142 and the bottom wall 144, and adjacent to the connecting wall 152. A cutout 153 is defined in a side of the blocking piece 150 facing the connecting wall 152. An inner side of each of the top wall 142 and the bottom wall 144 defines a sliding groove 154. The sliding grooves 154 are adjacent to a side of the blocking piece 150 opposite from the side defining the cutout 153.

The fixing member 16 comprises a bar 164, a pin 162, and a torsion spring 160. The torsion spring 160 comprises a main body 166 and two legs 168 extending from opposite ends of the main body 166, respectively. Two arms 172 extend from an inner side of a first end portion of the bar 164. A recess 176 is defined in an outer side of a second end portion of the bar 164, and a tab 178 is formed at the second end portion of the bar 164. The tab 178 extends slantingly from a bottom edge of the recess 176 in a direction away from the first end of the bar 164. Two projections 174 extend from distal ends of the arms 172 and away from the tab 178.

The latching member 18 comprises a plate 180, a first latching portion 182 formed at a first end portion of an inner side of the plate 180, and a second latching portion 184 formed at a second end portion of the inner side of the plate 180. The first latching portion 182 comprises two protrusions 186 extending from a top side and a bottom side of the plate 180, respectively. The second latching portion 184 comprises an extension piece 188 extending from the second end portion of the plate 180, and a resilient piece 190 extending slantingly from a top portion of the extension piece 188 toward a bottom portion of the extension piece 188. A block 192 protrudes from the inner side of the plate 180. An engaging hole 194 is defined in an inner surface of the first latching portion 182 and between the protrusions 186.

Referring to FIGS. 3 to 5, in assembly, the pin 162 is received through the top wall 142, one of the arms 172, the main body 166 of the torsion spring 160, and the other arm 172, and then one end portion of the pin 162 is received in the bottom wall 144, thereby pivotably mounting the fixing member 16 to the first end portion of the connecting portion 14. The legs 168 resist against the inner side of the bar 164 and the adjacent sidewall 12. In an original state, the bar 16 is slanted relative to the connecting portion 14, and the projections 174 are received in the receiving slot 140.

The latching member 18 is received in the second end portion of the receiving slot 140 and abuts an outer side of the blocking piece 150. The protrusions 186 are slidably received in the sliding grooves 154. The extension piece 188 and the resilient piece 190 abut an inner surface of the connecting wall 152. The resilient piece 190 further abuts an inner surface of the corresponding sidewall 12. In an original state of the latching member 18, the block 192 is received in the cutout 153.

The HDD 20 is mounted between the sidewalls 12 and to the connecting portion 14. The conversion card 30 comprises two inserting portions 32 to be received in the two through holes 120, respectively, and the conversion card 30 is electrically connected to the HDD 20.

After the mounting device 10 is received in a receiving space of a chassis (not shown), the fixing member 16 is pivoted toward the connecting portion 14. The tab 178 pushes the latching member 18 toward the connecting wall 152 to deform the resilient piece 190, and the block 192 extends out of the cutout 153. After the tab 178 passes over the plate 180, the resilient piece 190 is restored, and the plate 180 moves back to block the tab 178. The block 192 is received in the cutout 153 and blocked by the blocking piece 150. The tab 178 is engagingly received in the engaging hole 194. The legs 168 are deformed. At this time, the projections 174 are exposed out of the receiving slot 140 to be engaged in the chassis, and the mounting device 10 is fixed to the chassis.

In uninstalling the mounting device 10, the latching member 18 is moved toward the connecting wall 152 to remove the tab 178 from the engaging hole 194. The legs 168 are restored to push the second end portion of the bar 164 away from the connecting portion 14 and disengage the projections 174 from the chassis. Therefore, the mounting device 10 together with the HDD 20 is easily taken out of the chassis.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and various changes may be made thereto without departing from the spirit and scope of the description or sacrificing all of their material advantages, the examples hereinbefore described merely being exemplary embodiments.
